My grandson is about as many days as my son in weeks, and my grandson is as many months as I am in years. My grandson, my son and I together are 120 years. Can you tell me my age in years ?
Answers
y - your age in years
There are 52 weeks in a year and 365 days in a year, so the age of your grandson in years is (52x)/365
There are 12 months in a year, so the age of your grandson in years is y/12.
Set both expressions equal to each other:
Your son's age is equal to 365/624 of your age.
Your grandson, your son and you together are 120 years.
You are 72 years old.
Let m be my age in years.If s is my son's age in years, then my son is 52s weeks old. If g is mygrandson's age in years, then my grandson is 365g days old. Thus,
365g = 52s.
Since my grandsonis 12g months old,
12g = m.
Since my grandson,my son and I together are 120 years,
g + s + m = 120.
The above system of3 equations in 3 unknowns (g, s and m) can be solved as follows.
m / 12 + 365 m /(52 x 12) + m = 120 or
52 m + 365 m + 624m = 624 x 120 or
m = 624 x 120 /1041 = 72.
So, I am 72 yearsold.
The problem is hard...i don't know if you understood this..Hope i helped!

What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a county has 90 schools. The county received 992 new computers.
The required computers for 90 schools will be calculated as,
Computer required = 90 x 11
Computer required = 990
Available compters = 992
Remaining = 992 - 990 = 2 computers
Therefore, there are enough computers 992 to be distributed to 90 schools.

Answer:
1-ELIMINATION.
2- SUBSTITUTION.
3- GRAPHING.
Step-by-step explanation:
Methods:
1- Elimination:
- Line up the variables.
- To cancel out one of the variables, you need to make that the coefficient of that variable opposite. For example:
As you can see, the coefficient of x in the first eqation is 3 and -3 in the second option.
- Add the equations.
- Solve for the the variable that is still present.
- Substitute the value of the variable obtained into one of the original equations.
- Solve for the other variable.
2- Substitution:
- Solve for one of the variables from any of the equations of the system.
- Substitute into the other equation for that variable.
- Solve for the other varible to find its value.
- Substitute the value obtained into any of the original equations and solve for the other variable.
3- Graphing:
- Rewrite the equations as equtions of the line slope intercept form (, where m is the slope nd b the y-intercept).
- Graph each line.
- Then:
If there ir an intersection point of the two lines, then that point is the solution to the system
If the lines are the same, there are infinitely many solutions.
If the lines are parallel, then there is no solution
